More than 5,000 years ago, the Chinese discovered how to make silk from silkworm cocoons. For about 3,000 years, the Chinese kept this discovery a secret. Because poor people could not afford real silk, they tried to make other cloth look silky. Women would beat on cotton with sticks to soften the fibers. Then they rubbed it against a big stone to make it shiny. The shiny cotton was called "chintz." Because chintz was a cheaper copy of silk, calling something "chintzy" means it is cheap and not of good quality.
